I noticed (but was too busy to talk about it earlier) the initial design
does not allow easily the background animation. You added a window to
the wall for this... If it is a jail window, maybe it should have some
bars?

If we are going to use the animation feature in Fedora 9 (I think we
should. A lot of people commented on it, some thought Fedora broke their
monitor and it probably will be in upstream GNOME), then a chain slowly
breaking free over time might be a cool thing.
